SteamOS Update 126 Pushed To Alchemist Beta

Posted by , / 4450 views
On July 30th John Vert Published the details of the latest changes to the SteamOS Beta. Most notable in this release are additional packages that XBMC requires as well as more compositor bug fixes.

To me it's nice to see that Valve is working, or at least helping third-party programs run on SteamOS out of the box. That's a step in the right direction as it could remove some accidental repository corruption by less experienced users. What do you guys think?

The full change log as well as the thread think can be found below.

Changes:

QuoteAdd additional packages needed by XBMC
acpi-support - upstream security fixes CVE-2014-1419
apache2 - upstream security fixes CVE-2014-0226, CVE-2014-0231,

Do you find, with all these compositor fixes, that SteamOS does a better job with screen tearing than stock Ubuntu?

I use stock Ubuntu, Nvidia proprietary, with Unity. I have very few problems with using Linux for gaming, but I do occasionally see some games experience screen tear. Not all games, and not so severe that I'm prepared to run crazy Openbox/Compton combos to eliminate it, but it's about the last thing I'd like to see fixed in my gaming experience.

Personally I don't use Ubuntu, but I can say that SteamOS is better than XFCE stock (without compton). That might be an interesting video to make though.

I use XFCE for my gaming rig and it is among the worst for screen tearing (with compton its a whole different story). LXDE is also a similar case. I have KDE on my laptop and get no tearing on that whatsoever.

Before I installed compton on Xubuntu, I used the SteamOS session on the login screen, which gave 0 screen tearing and marginally better FPS. Might be a good solution for you (good if you want to try SteamOS without doing a full istall too): http://linuxg.net/how-to-install-the-steamos-session-on-ubuntu-14-04-trusty-tahr/[quote=scaine]Do you find, with all these compositor fixes, that SteamOS does a better job with screen tearing than stock Ubuntu?

Y'know, I wondered if you could start a SteamOS session without having to boot fully into that environment. Great find - thanks!

I've experienced that SteamOS has no tearing, compared to miscellaneous tearing on regular Ubuntu like you describe, although I've only used the steamos-session. SteamOS-session doesn't manage logging in and out and switching logins particularly well though, I experienced quite a few hangs and reboots. However once you're in SteamOS-session, everything works fine.
